Incubation and hatching conditions of laying hen chicks explain a large part of the stress effects from commercial large-scale hatcheries

Louise Hedlund et al.

Summary: In commercial egg production, laying hen chicks are exposed to various stressful events during incubation, hatching, and their early life, which can impact their behavior and stress sensitivity. This study found that incubation and hatching alone can cause long-term stress effects in chickens, and further processing exacerbates these effects to some extent.

High and low feather pecking selection lines of laying hens differ in response to a judgment bias test

Katarina Pichova et al.

Summary: This study compared the cognitive performance of high feather pecking (HFP) and low feather pecking (LFP) hens in a visual discrimination task and judgment bias test, finding that HFP hens showed higher motor impulsiveness in decision making, but were more optimistic and approached ambiguous stimuli faster.
